Sigma 7

User Summary
Problems at Space Station Sigma 7! All robots have gone beserk, and you have to fix them at the central computer!

The game is divided into three parts:
First you fly to the space sataion, in a diagonally scrolling shooter game where you have to shoot down the protective mines.

Then inside the Sigma 7, you use the security tank through the maze of halls in the space station. Pick up enough of the glowing balls laying around (much like in Pac-Man, but you don't need all the balls), shoot enemies.

And the last level there is a pattern recognition game.

After completion the game restarts with harder, better, faster, stronger enemies.
